Efekty urbanizace a atmosférické chemie v modelování klimatu
No full textTitle: The effects of urbanization and atmospheric chemistry in climate modelling Author: Jan Karlický Department: Department of Atmospheric Physics Supervisor: doc. RNDr. Tomáš Halenka, CSc., Department of Atmospheric Physics Abstract: This work is dealing with the modelling of the climate on the regional scale with an emphasis on the impact of urban areas on the local climate or simply urban climate. The importance of the impact of urban surfaces on the local climate and living conditions is discussed in detail in theoretical sections, followed by the model study showing all consequences of the urban climate. The results showed that all models and urban parameterization used are able to reproduce the summer evening and nocturnal urban heat island with the magnitude of 2- 3 o C. The impact of cities on other meteorological variables depends more on the urban parameterization used. The urban induced changes have mostly a positive effect on the weather conditions with regards to the pollutant dispersion. Further, the thesis also deals with the modelling of atmospheric chemistry on the regional scale. Modelled ozone concentrations match the observation quit well, while the simulated concentrations of other gases are highly underestimated.

RNDr. Tomáš Halenka, CSc., Katedra fyziky atmosféry Abstrakt: Tato práce se zabývá modelováním klimatu na regionálním měřítku s důrazem na vliv městských oblastí na místní klima či souhrnně klima města. Výz- nam vlivu městských povrchů na místní klima a životní podmínky je podrobně probrán v teoretických částech práce, následující modelová studie popisuje další specifika spojená s klimatem města. Její výsledky ukazují, že všechny užité mod- ely a parametrizace města jsou schopny zachytit letní večerní a noční městský tepelný ostrov o intenzitě 2-3 o C. Vliv měst na další meteorologické prvky se podstatně liší v závislosti na použité parametrizaci městského prostředí. Měst- ské povrchy mají převážně pozitivní vliv na rozptylové podmínky. Práce se také zabývá modelováním atmosférické chemie na regionální úrovni, výsledné mode- lové koncentrace ozonu se dobře shodují s měřeními, avšak modelové koncentrace dalších hodnocených plynů jsou výrazně podceněny. Klíčová slova: regionální klimatické modelování, klima města, troposférická chemie 1Department of Atmospheric PhysicsKatedra fyziky atmosféryFaculty of Mathematics and PhysicsMatematicko-fyzikální fakult

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
ELEVEN FACES OF JAN GOGOL, JR.
No full textAuthor Jan Rendl in his thesis attempts to look at the world of ideas and educator Jan
Gogola ml. through the eleven chapters in which each chapter somehow characterizes itself by Jan Gogola ml. and each of them somehow determines its creative ideas of it through the metaphor of a football match when Jan Gogola, with its characters, movies himself a teammate, as well as defensively. It gives goals with their situations as well as occasionally digging his opponents ankles.
Jan Gogola ml. thus embodies one stage of the Department of Documentary Film at FAMU, which often stands at the intersection between teaching activities and Karel Vachek among students who applied by them during their seminars psychological methods that work must be peculiarly associated with the author of the film

Estimation of Primaries and Multiples by Sparse Inversion
No full textSurface-related multiple reflections are often considered noise in the seismic reflection measurements. By seismic processes, such as migration and inversion, they can be mistakenly seen as primary reflections and give an erroneous image of the earth. Therefore, a method is needed to separate the multiples from the primaries. This thesis describes a primary estimation method named estimation of primaries by sparse inversion (EPSI). The interesting aspect of this method is that it does not see the multiples as noise, but uses the multiples to come to a better estimation of the primaries. Other wave equation based primary estimation methods first predict the multiples and then adaptively subtract them from the data. During this adaptive subtraction primary energy may be removed. EPSI tries to explain the total data, both primaries and multiples, in terms of primary impulse responses. By doing so an adaptive subtraction of multiples is avoided. In fact EPSI is a large-scale inversion process that estimates primaries such that they and their corresponding multiples explain the total data. To constrain this process, a sparseness constraint is used, which assumes that our estimated primaries have a certain amplitude distribution (large and small ones). A general characteristic of wave equation based primary estimation methods is that the near-offset data are very important for estimating water column reverberations, especially in shallow water. However, it is not possible to record the near-offset data and, therefore, most wave equation based primary estimation methods have great difficulties with shallow water marine data. A major advantage of EPSI is that it can reconstruct the missing near-offset data from information in the multiples and, therefore, show a good primary estimation result on shallow water marine data. Furthermore, the EPSI method can be extended to other measurement configurations, exploiting a similar relation between primaries and surface multiples. In this thesis both passive and blended seismic data have been considered. For passive seismic data multiples are used to obtain an estimate of the subsurface responses, usually by a cross-correlation process. This cross-correlation process relies on the assumption that the surface has been illuminated uniformly by subsurface sources in terms of incident angles and strength. If this is not the case the cross-correlation process cannot give a true amplitude estimation of the subsurface response. Furthermore, there are cross terms in the cross-correlation result that are not related to actual subsurface inhomogeneities. In this thesis it is demonstrated that, with some modifications to the algorithm, EPSI can obtain true amplitude subsurface responses without the uniform surface illumination assumption. The EPSI method will go beyond the cross-correlation process and will estimate primaries only from the multiples in the available signal. The estimated primary impulse responses, with point sources and receivers at the surface, can be used directly in traditional imaging schemes. This thesis demonstrates that for the situation of blended acquisition, meaning that different sources are shooting in a time-overlapping fashion, multiples can be used to 'deblend' the seismic measurements. With some modifications the EPSI method can be used for blended seismic data. As output EPSI gives unblended primary impulse responses with point sources and receivers at the surface, which can be used directly in traditional imaging schemes. The feasibility of the EPSI method is demonstrated in this thesis by a successful application of the method to two marine field datasets, one with a moderate water depth and one with shallow water. It demonstrates that for deeper water EPSI can compete with the standard surface-related multiple elimination (SRME) method, where for the shallow water EPSI clearly shows better results than SRME. The latter is mainly attributed to the fact that near offset reconstruction, which plays a crucial role in shallow water data, is included in the EPSI method.Imaging Science & TechnologyApplied Science

The Theological Work of Jan Valerián Jirsík
No full textAnglická anotace The theological work of Jan Valerian Jirsík Jan Hamberger This thesis deals with the theological work of the Czech 19th century author Jan Valerián Jirsík (1798-1883). Its first part consists of an introduction into the Czech historical context of the 19th century and the life of the author. Its second part presents a survey of the literary-theological work of Jirsík in three life phases: the first phase is demarked by his activity as chaplain and vicar, the second phase by his editorial activity for Casopis pro katolické duchovenstvo (trans. Magazine for catholic clergy) and the last phase by his pontifical years in the diocese of Southern Bohemia. His literary work is divided by theme into various periods, shortly described and characterized. The last and major section of this thesis deals with the most comprehensive and renown work of Jan Valerián Jirsík - Populární dogmatika (trans. Popular doctrine). This pivotal work of theologian Jirsík is discussed at large and analyzed by tractate, both apologetic and dogmatic. The conclusion expresses the prevailing character of the entire work of Jirsík and its significance. Key words: Theology Apologetic theology Dogmatic theology Theological literature Catholic Churc
